He was arrested after he tried to remove the cop’s service weapon by grabbing its handle, the document said.

He told agents he lived in Hoboken, New Jersey, and had been planning an assassination for about a year. He drove from New Jersey to California before coming to Las Vegas last Thursday, according to authorities.

He had a British driver’s license, federal agents said. Sandford said he was sure he would die in his attempt to kill Trump, and that he had gone to the Battlefield Vegas shooting range on Friday to learn how to fire a weapon, the complaint said.
